Timed voltage clamp for battery charger |
摘要 |
A battery charging device wherein the charging current level is controllable by a thermal circuit responsive to battery temperature also includes a circuit responsive to battery voltage and a timing circuit. The timing circuit is activated when a battery is inserted into the device for charging and immediately times a very brief interval. If the battery voltage exceeds a predetermined level during the timed interval, the charging current level is reduced as by the thermal circuit. The circuit protects both cold and charged batteries from damage due to overcharging.
